3 Claims. I

lThis invention relates to'artiflcial bait of the type in which bladesare 'provided forimparting a spinning movement to the bait. 1

The kinvention has for its object to provide means actuated each timethe fishing line is thrown for reversing the pitch .of the blades andthedirection of ;spinning.movement of the bait so as to avoid theobjectionable consequences of continuously twisting the line in onedirection.

In the accompanying drawingwherein an approved embodiment of theinvention is illustrated,

Figurel is a longitudinal sectional view through the bait;

Figure A2L is'a view similar to Figure l taken at right angles `theretoand partly in side elevation;

l.Figure 3a is a fragmentary side elevation view showing Lthe blades inone position;

Figurebdis a view similar to Figure 3a but showing the bladesin anotherposition;

Figure V4 is an end elevation of the invention;

Figure 5 is an enlarged fragmentary view corresponding to Figure r2;

Figure 6 is an enlarged fragmentary View corresponding to Figure l; and

Figure 7 is a cross sectional view with parts removed taken on line 'I-lof Figure 6.

Referring to the drawing in detail, the numeral I designates a bodyhaving a central chamber therein and preferably tapered at the endindicated at 2 and rotatably supporting a diametrical shaft 3 rotatablymounted in the body I and provided with blades 4 and l5 fixed to theshaft and located on opposite sides of the body so as to impart a,spinning movement thereto when the bait is drawn through the water.

The shing line (not shown) is attached through the eye 6 at the outerextremity of a stem 1 slidably mounted in the body I. The stem 'Iterminates within the central chamber of the body and. is connected by abail 9 with one end of`a coil spring 8, the opposite end of which isattached to a rod I5 looped at its opposite ends and thereby securedagainst longitudinal movement in the body I. The tension of the spring 8normally tends to move the slidable stem 'I inwardly and the movement ofthe latter is limited in opposite directions by the terminals of slots Iformed in the opposite sides of the bail 9 and coacting with the shaft 3which passes through said slots.

The upper exposed extremity of the rod I is connected in a suitablemanner with one or more'sh hooks such as indicated at I 6.

vBetween the opposite sides `4of 'the `bail A9 All-a ratchet lWheel vIIlhaving four vteeth thereon TAisu rigidly secured to the shaft 3 and-the shaft, together with the vblades 4 and 5 secured thereto, is heldin an angular position to which itis' moved by the tension-of a springlfsecured-.to the stem 'I and lying against two adjacenttee'th oftheratchet wheel II. A spring pawl I3 hav'- ing 'an Aangular end I7 is`engaged with the side of theratchet wheel II opposite the retainingspring I4. As indicated in Figure 7 the ba'ilf and'the spring arms arepreferably formed-from a single'piece of sheetmetal ofcruci-formvconfiguration and the fourrespectivearms are bent upward outof the plane of the metal asindicated'in the drawing. 'In' Figure '7 thewasher'foij the nut and the'threaded extensionrofthe stem I have beenomitted for purposes of clarity.

Two of the arms constitute the bail 9, while' the other two arms I3 andI4 are respectively bowed at I2 and I2' adjacent their inner ends toprovide resiliency so that they respectively constitute the spring pawland the retaining spring. The threaded section I8 of the stem 'I extendsthrough' a hole in the central portion of the metal piece whichconstitutes the base from which projects the bail 9 and the oppositelyarranged spring pawl I3 and retaining spring I4 and a nut I9 cooperateswith this threaded section to hold the assembly of arms against a collar2B on the stem.

The end I'I of spring pawl I3 cooperates with the teeth of the ratchetwheel or toothed pinion II and thereby turns the shaft 3 through anangle of each time the stem I is moved outwardly through the body. Theretaining spring I4 secures the ratchet wheel II in quarter turnposition. The successive forward strokes of the slidable stern 'I alwaysrotate the shaft 3 in the same direction. The blades 4 and 5 are sodisposed with respect to the teeth of the ratchet wheel I I that whenthe latter is turned incident to longitudinal movement of the stem 1,the pitch of the blades is reversed from the position which theyformerly occupied, and hence the body I is caused to spin in theopposite direction.

In use, the artificial bait is attached to the fishing line (not sho-wn)and in throwing or casting the bait a longitudinal pull is exerted onthe slidable stern "I, and the latter moves outwardly against thetension of the spring 8, and in so doing the pawl I3 is caused to turnthe shaft 3 and the blades and 5. Thus each time the articial bait isthrown, the pitch of the blades 4 and 5 is reversed thereby avoiding thecontinuous spinning of the bait in one direction and the 3 objectionableconsequences of twisting the iishing line.

What we claim is:

1. An artificial bait comprising a body, pitched blades mounted on theoutside of said body, means for varying the pitch of said bladesincluding a reciprocable member extending into said body and adapted atan exposed end to receive a line, said pitch varying means including afour tooth pinion drivably connected to the blades and means positionedon one side of the pinion and carried by the reciprocable member forrotating said pinion successive quarter turns in one direction forreversing the pitch of the blades and thereby the rotational movement ofthe bait, coacting means positioned on the other side of the pinion andalso carried by the reciprocable member for frictionally engaging thepinion and maintaining saidblades in temporarily fixed position betweenthe quarter turn rotation thereof in one direction, and means connectedto the reciprocable member for normally returning same to an initiallypredetermined position.

2, An articial bait comprising a body having a curved nose and a chamberwithin the body, a pull member extending through the nose andreciprocable within the chamber adapted to receive a line at its frontend and secured to the rear of the body by a biasing spring, a shaftpositioned transversely of the body and having oppositely pitched bladesiixed on either end exteriorly of the body, a four tooth pinion on saidshaft, and a leaf spring having spaced top and bottom leaves mounted onsaid pull member, said bottom leaf frictionally engaging the pinion,said top leaf being shorter and having a curved end for engaging thepinion and rotating same by quarter turns in the same direction as thepull member is moved longitudinally of the body to change the pitch ofsaid blades to thereby effect reverse rotation of the body as the sameis drawn through the water.

3. An artificial bait comprising a body having a curved nose and achamber within the body, a

' in the longitudinal slots in said structural members, oppositelypitched blades fixed on the opposite ends of said shaft and positionedexteriorly of the body, a four tooth pinion on said shaft and disposedintermediate the structural members. and a leaf spring having horizontaltop and bottom leaves mounted on said pull member, said bottom leaffrictionally engaging the pinion, said top leaf being shorter and havinga curved end for engaging the pinion and rotating same by quarter turnsin the same direction as the pull member is moved longitudinally of thebody to change thepitch of said blades to thereby effect reverserotation of the body as the same is drawn through the water.
